Deposition of calcium phosphate or oxalate crystals in the breast, detectable in mammograms. Histologic granular/amorphous-type calcifications formed by deposition of calcium on nuclear debris are often present in ductal carcinoma in situ with necrosis. These form linear, branching patterns on X-rays. Radiologists use the American College of Radiology Breast Imaging Reporting and Data System (BIRADS) classification to describe calcifications.

Small calcium deposits within the breast, singly or in clusters, that are usually found by mammography. These are also called microcalcifications and macrocalcifications. They are a sign of change within the breast that may be monitored by additional, periodic mammograms, or by immediate or delayed biopsy. They may be caused by benign (non-cancerous) breast conditions or by breast cancer.

Calcium deposits are the byproduct of cell division; common in breast tissue, but if found in clusters they are called microcalcifications and may indicate the beginning of breast cancer; the only way to determine if they are can­cerous is to remove them; most of the time they are caused by benign changes.

Small deposits of calcium in breast tissue. Calcifications usually can't be felt, but they appear on a mammogram. Macrocalcifications (coarse calcifications) are usually not associated with cancer. Microcalcifications (fine calcifications) are usually benign but can sometimes indicate the presence of an early breast cancer when they are found in certain clusters.

Calcium deposits appear on a mammogram as tiny white dots, lines or coarse white flecks. These may occur as the breast tissue changes with age. The radiologist will interpret the significance of the calcifications by their appearance and pattern.

The deposition of calcium salts in body tissues. In the breast, it can be associated with either normal or cancerous tissue.Calcium deposits within the breast, singly or in clusters, often found by mammography.
